Description: BACKGROUND OF THE INVENTION (Field of Industrial Application) The present invention relates to a transfer device that automatically and accurately performs a work of turning over a part and transferring it to a predetermined position.

(Prior Art) Conventionally, as a method of transporting parts such as PGA pins from a parts feeder using a linear feeder, and inverting the parts to a predetermined position, as shown in FIG. Suction the parts 1 'one by one from the outlet of 2'
There is a method of inverting and transporting to the PGA substrate 9 '.

(Problem to be Solved by the Invention) However, in such a conventional example, there is a problem that a suction error occurs due to vibration of components on the linear feeder and overlap near the outlet.

The present invention has been made in view of the above points, and an object of the present invention is to provide a transport device capable of automatically and accurately reversing and transporting individual components.

(Means for Solving the Problems) According to the present invention, there is provided a linear feeder that conveys a component, and a plurality of notches facing an outlet of the linear feeder are formed in a circumferential direction, and the notch portion receives the component. A first rotating disk, and a component that is rotatably provided below the first rotating disk and in a plane substantially orthogonal to the first rotating disk and that is positioned in the notch and adsorbs the component from the notch. A second rotating disk provided with a plurality of suction portions to be held along a circumferential direction, wherein each of the suction portions can be reciprocated in a substantially radial direction of the second rotating disk. In addition, the second rotating disk achieves the above object as a configuration in which the notch formed in the first rotating disk rotates in the opening direction of the notch.

(Operation) In the above means, a first rotating disk is provided in which a plurality of notches facing the outlet of the rectilinear feeder for transporting components are formed in the circumferential direction. When the first rotating disk is rotated, a plurality of notches sequentially face the notches of the linear feeder, and each notch receives a component.

In the present invention, the second rotating disk is provided rotatably below the first rotating disk and in a plane substantially orthogonal to the first rotating disk. The second rotating disk is provided with a plurality of suction portions along the circumferential direction which are capable of sucking and holding the components located in the notch from the notch and reciprocating substantially in the radial direction of the second rotating disk. Are provided.

When the second rotary disk is rotated in the opening direction of the notch, one of the plurality of suction portions is located below the component located in the notch in a state of being integrated with the second rotary disk. Move towards. In this state, one suction part moves upward, that is, moves outward in a substantially radial direction, and moves to a state in which it approaches a part located in the notch. For this reason, the part is reliably sucked by the one suction part, and the part sucked by the one suction part is turned over by rotating the second rotating disk further in the opening direction of the notch. Become.

Hereinafter, the present invention will be described in detail with reference to the drawings showing examples.

1 and 2 show one embodiment of the present invention, in which 1 is a component such as a pin for a PGA, 2 is a vibration feeder as a linear feeder for transporting to a component transfer device, 3 is a vibration feeder 2 4 is a rotary disk that is installed on the same line and rotates intermittently, 4 is a suction head as a suction unit, 5 is a suction head
This is a rotating disk that holds and rotates intermittently.

In this vibration feeder 2, as shown in FIG. 1, a groove 2b is formed along the longitudinal center line of the upper surface, and the component 1 slides and is guided by the vibration of the vibrating portion 2a in the groove 2b, thereby conveying the component. It is formed so as to be conveyed to an outlet 2c that is in sliding contact with the device. As shown in FIG. 1 (a), this component 1, for example, a PGA pin, has a disk-shaped flange portion 1b formed above the central shaft portion 1a, and this flange portion 1b is engaged with the upper edge of the groove portion 2b. It has been stopped.

The component conveying apparatus mainly comprises a first intermittently rotating rotary disk 3 which is disposed on the side of the outlet 2c of the vibration feeder 2 and which is arranged in a substantially horizontal direction in the state shown in FIG. Notch 6 gripping component 1 formed on the outer periphery
A suction head 4 for sucking the component 1 and a second rotating disk 5 having a plurality of suction heads 4 and intermittently rotating and arranged substantially perpendicular to the rotating disk 3.

The rotating disk 3 is rotatably supported at the center thereof by a rotating shaft 3a, and is intermittently rotated in the reverse clockwise direction by the driving of a driving source (not shown) connected to the rotating shaft 3a. The notches 6 are formed on the outer periphery of the rotating disk 3 at equal intervals along the outer periphery (in this embodiment, eight equal portions of the outer periphery).

And a notch located at the outlet 2c of the vibration feeder 2.
The suction head 4 is arranged vertically below the notch 6b opposite to 6a so as to be able to move up and down (to reciprocate substantially in the radial direction of the second rotating disk 5). The rotating disk 5 holding the suction head 4 has a rotating shaft 5a pivotally supported at the center, and is driven by a driving source (not shown) connected to the rotating shaft 5a to rotate and rotate the rotating disk 3 at a timing. The watch rotates intermittently in the clockwise direction while adjusting

The rotating disk 5 is arranged at a position where the suction head 4 moves in the opening direction of the notch 6b of the rotating disk 3.

2A is a view of the component conveying apparatus of the present invention as viewed from the front of the rotary disk 5, FIG. 2A is a perspective view of the suction head 4, and reference numeral 8 is a nozzle hole. Next, the operation and operation of the component transport device of the present invention will be described.

First, as shown in FIG.
1 supported in a suspended state, for example, PGA
The pins are sequentially selected along the groove 2b by the vibration of the vibrating portion 2a and reach the outlet 2c. A gap is provided between the vibration feeder 2 and the rotating disk 3 so that vibration is not transmitted to the rotating disk 3 and the outer periphery of the rotating disk 3 faces the outlet 2c.

The notch 6a of the rotary disk 3 faces the outlet 2c at the position A in FIG. 1 and stands by in an empty state, and the component 1 of the outlet 2c is pushed into the notch 6 by vibration. (C) is held by being sucked by the suction port 7 and does not come off from the notch 6 during the next rotation of the rotating disk 3.

The part 1 thus taken out at the position A and held in the notch 6 is supplied to the positions B, C, D and E in the reverse rotation direction of the timepiece. That is, at the position E, as shown in FIG. 2, after the delivery process with the rotary disk 5 is completed, the rotary disk 3 is rotated to be empty and the notch is formed.
6b stops at the F position. During this rotation, the outer peripheral surface of the rotating disk 3 blocks the outlet 2c of the vibration feeder 2,
The component 1 can be prevented from falling. Next, a delivery operation when the component 1 is supplied to the position E will be described.

As shown in FIG. 2, the suction head 4 of the rotating disk 5
It is waiting in the empty state below the component 1 at the delivery position (the position E in FIG. 1) in the vertical direction. The suction head 4 is pushed upward by a driving source (not shown) (operation A), and the lower part of the component 1 is inserted into the nozzle hole 8 of the suction head 4.
The component 1 is sucked and held at the same time as the component 1 is inserted into the nozzle hole 8, and does not separate from the suction head 4 during the next rotation of the rotating disk 5.

The component 1 held by the suction head 4 at the P position as described above is supplied to the Q position by the rotation of the rotary disk 5 (B operation). During the B operation, the suction head 4 pushed upward at the P position is returned to the original position.
The suction head 4 at the Q position is further supplied to the R position, and performs a transfer operation to the next step, for example, a press-fit operation (D operation) into the PGA substrate 9. After the transfer operation, the suction head 4 is sequentially supplied to the S position and the P position, returns to the original state, and is supplied to the next transfer operation.

In the above-described embodiment, the description has been made only for the component transfer apparatus including the rotary disk 3 having eight notches 6 and the rotary disk 5 having four suction heads 4. However, the present invention is not limited to this. Instead, it is also possible to provide eight or more notches and four or more suction heads, and it is also possible to provide a plurality of vibration feeders.

Further, it is needless to say that the present invention can be applied to a component transport device that transports components other than the PGA pins.

In the above embodiment, by rotating the rotary disk 5 in the opening direction of the notch 6 where the component 1 sucked by the suction portion 4 is located, the component 1 sucked by the notch 6 is cut off.
Since the rotation force of the rotating disk 5 is a force that overcomes the suction force of the component 1 on the rotation disk 3, the components vibrate even if both the rotation disk 3 and the rotation disk 5 are constantly maintained in the suction state. There is an effect that the component 1 from the feeder 1 can be transported in an inverted state (see the position D in FIG. 2).

(Effects of the Invention) As described above, according to the component transport device of the present invention,
A linear feeder that conveys the component, a plurality of notches facing the outlet of the linear feeder formed in the circumferential direction, a first rotary disk receiving the component at the notched portion, and a first rotary disk for receiving the component. A plurality of suction portions are provided along the circumferential direction, rotatably provided below and in a plane substantially orthogonal to the first rotating disk, and holding the components located in the notches by suctioning from the notches. And a second rotating disk provided with the second rotating disk, wherein each of the suction portions can reciprocate in a substantially radial direction of the second rotating disk, and the second rotating disk is the second rotating disk. Since it is configured to rotate in the opening direction of the notch formed in the first rotating disk, it is possible to automatically and accurately perform the operation of inverting the part through the second rotating disk and transporting it to a predetermined position. There is an effect that can be done.
